I don't follow the reasoning there. Row cache or fs cache, it will be hot after reading it once, the difference is that doing a read to the cached data is much faster from row cache. >> 4.

FWIW, you don't have to wait for 0.7 to turn this off (see http://www.riptano.com/blog/whats-new-cassandra-066). However, to pin affinity to a single replica you will need SimpleStrategy from 0.7. -- Jonathan Ellis Project Chair, Apache Cassandra co-founder of Riptano, the source for professional Cassandra support http://riptano.com
